- Primary Outcome Measures
Name Time Method Gastric emptying time 1 hour The time for digesting a meal
- Secondary Outcome Measures
Name Time Method Cross sectional area of the stomach At 4, 5, 6, 7, and 8 hours after eating a meal. The cross sectional area of the stomach is assessed by using ultrasonography in the supine and right lateral positions.
Incidence of full stomach At 4, 5, 6, 7, and 8 hours after eating a meal. The incidence of full stomach is assessed by using ultrasonography.
Gastric volume At 4, 5, 6, 7, and 8 hours after eating a meal. The volume of stomach is assessed using the following formula; volume of stomach (mL) = 27.0 + 14.6 x cross-sectional area (right lateral position) - 1.28 x age.
Type of gastric contents At 4, 5, 6, 7, and 8 hours after eating a meal. The type of gastric contents is assessed using ultrasonography.
